Distances are measured slope distance to face of the tree at DSH.

All live conifer trees within the subdivision, including boundary trees, greater than or equal to minimum DBH in A.2 count towards residual stocking.

These specifications apply only to trees that meet the minimum tree diameter stated in A.2.

For all trees that meet A.2 log removal specifications All Subdivisions (1-25)

End Result: After treatment, these areas will have an average stand density 40 ft2 per acre of basal area (excluding ponderosa pine ≥ 21” DBH and 26” DSH) and increased variability in the structure and spatial arrangement of the residual trees in the form of individual trees, clumps, openings, and retention patches. The residual area will have an increase in its mean diameter, a reduction in ladder fuels, as well as a shift in composition and structure towards mature trees, larger trees, fire-adapted conifers, and other desirable species.

A basal area factor of 10 will be used to determine stocking compliance.

Residual stocking objectives: Perform these in order; subsequent objectives do not override any before them:

1. Retain all five-needled pine, hardwoods, orange-marked trees, mature trees (see figures below), and ponderosa pine greater than or equal to 21” DBH and 26” DSH. Because this is the first objective in this list, no other objective can override this requirement.

2. Remove all western juniper.

3. Within 30 feet of healthy, large (≥ 21” DBH) ponderosa pine and five-needled pine, cut all lodgepole pine

<21” DBH or 26” DSH, and all white fir.

4. Within 50 feet of an aspen clump, thin to 30 ft2 per acre basal area, with an acceptable range of 20-40 ft2 per acre. Five-needled pine and ponderosa pine ≥ 21” DBH and 26” DSH count towards residual BA within these buffers.

5. Where timber units overlap with Cut, Skid, Deck – Control Features, thin stand to a residual BA of 40 ft2 per acre, with an acceptable range from 30-50 ft2 per acre. Five-needled pine and ponderosa pine ≥ 21” DBH and 26” DSH count towards residual BA within Control Features.

6. Where current conditions are at ≤ 20 square feet per acre basal area of ≥ 21” DBH and 26” DSH ponderosa pine, thin stand to a target basal area of 50 square feet per acre with an acceptable range of 30-70 square feet per acre, not counting ≥ 21” DBH and 26” DSH ponderosa pine towards target basal area. Where current conditions are at ≥ 30 square feet per acre BA of ≥ 21” DBH and 26” DSH ponderosa pine, thin stand to a target basal area of 30 square feet per acre with an acceptable range of 20-50 square feet per acre, not counting ≥ 21” DBH and 26” DSH ponderosa pine towards target basal area. Because this is the last objective in this list, previous objectives can override this requirement.

Tree selection objectives:

1. Cut trees shall be selected by thinning from below so that the residual stand will be comprised of healthy dominant and codominant trees. Species preference for leave trees from highest priority to lowest is five-needled pine, ponderosa pine, incense-cedar, white fir, and lodgepole pine.

2. Do not leave trees with one-sided crowns. When two or more trees have developed one-sided crowns due to proximity, either cut or retain all to meet the desired stocking level.

Page 31 of 41 AMENDMENT 003 Bly Ranger District the inspection will also evaluate compliance with prescription requirements pertaining to selection of species, quality of leave trees, and spacing or juxtaposition standards for these subdivisions included in provision C2.355#.

Inspections will occur on at least 10% of the subdivision acreage in the sale.

Plot Intensity Table:

Subdivision Size

Minimum Plots/Unit

1-20 acres 1 plot per 2 acres 5

21-50 1 plot per 5 acres 5

51-100 1 plot per 10 acres 5

101+ Variable 10

Inspection plots require at a minimum recording for each in-tree using a 10 Basal Area Factor (BAF) of its (1) species, (2) DBH, (3) height, and (4) clump status (Individual, Small Clump, Medium Clump, Large Clump, N/A).

Refer to C2.355# for definitions. All general sale inspection methodology will follow the Pacific Northwest Timber Product Accountability Action Plan and the 2022 Fremont-Winema Timber Accountability Action Plan unless otherwise agreed to by the Forest Service.

C6.405 - ALTERNATE REMOVAL OF INCLUDED TIMBER (05/2005)

Contractor and Forest Service may agree to alternate removal requirements of Included Timber contained in A2.

Alternate removal requirements are to be set forth in an agreement signed by both Contractor and Contracting Officer. The terms of the agreement bind both parties and becomes part of the stewardship contract.

The development and execution of the agreement is based upon the determination by the Contracting Officer that removal of Included Timber is economically impractical if Contractor has no ready market for such logs in the tributary area. A tributary area is defined as the area in which the Contractor and competitors regularly deliver saw logs, or 200 miles from the Contract Area, whichever distance is greater.

The agreement for alternate removal requirements shall be executed prior to removing any timber from the Subdivisions included in the agreement. Alternate removal requirements shall apply only to whole units and not to portions of units. All material meeting alternate removal specifications shall be cut and removed to locations designated in the agreement.

Volumes of material with alternate removal requirements will be determined from the National Cruise report for the project. Contractor will be charged for the following:

C6.7 - SLASH DISPOSAL (03/2017)

As used in the following Subsections, the term "slash" is vegetative debris including, but not limited to, cull logs, blasted or pushed-out stumps, chunks, broken tops, limbs, branches, rotten wood, damaged brush, damaged or destroyed reproduction, saplings or poles, resulting from Contractor's Operations, including construction of roads or other improvements under this contract. Slash resulting from the construction of Specified Roads shall be disposed of as provided for in Section 201 of the Standard and Special Specifications and as shown in Drawings.

Any burning of slash or refuse by Contractor is subject to C7.201.

Forest Service may agree to substitute methods of slash disposal if such substitute methods will give equally satisfactory results.

Forest Service may waive specific slash treatment requirements of the Contractor. Contractor's Integrated Resource Account will be charged for any slash treatment requirements waived. The amount of such charges will be determined by Forest Service prior to felling operations in each Subdivision.

C6.74# (Option 2) - SLASH TREATMENT REQUIREMENTS (06/2008) Contractor shall pile, burn, yard, construct firelines or otherwise treat slash defined in C6.7, within designated areas. Work required of Contractor shall be in accordance with the following slash plan and specifications, and the Contract Area Map.

Unless otherwise agreed, or shown in the attached slash plan or specifications, when Included Timber is removed during Normal Operating Season, required slash work shall be completed within 30 days of removal of approximately three quarters of the volume in the unit. When Included Timber is removed outside Normal Operating Season, required work will be completed within 30 days of the beginning of the next Normal Operating Season.

See following specifications.

SPECIFICATIONS PURSUANT TO C6.74# - SLASH TREATMENT REQUIREMENTS (OPTION 2) (06/2008)
